BILLUND, Denmark — Brent Waller spent his childhood crafting plastic-brick versions of
characters from TV shows and movies such as
Teenage Mutant Ninja Turtles and
Batman. At age 35, the Australian Lego fan has become so good at playing with the toys
that the company will start selling his models.

Waller’s set of models — which includes a miniature of the Cadillac ambulance from
Ghostbusters, the 1984 comedy starring Bill Murray — will hit shelves in June and sell for
$49.99 in the United States. His set is one of six to come from a Lego crowd-sourcing website where
consumers can propose designs.

“It’s any Lego fan’s dream to have an official set they created,” said Waller, a video-game
developer in Brisbane. “It’s literally a childhood dream come true.”

Lego, the world’s second-biggest toymaker, has run its initiative since 2008 with help from a
Japanese crowd-sourcing website called Cuusoo System.

Any Lego Cuusoo project that gets more than 10,000 votes is evaluated by the company for
suitability.
